Display device including pads formed separately from display panel

Abstract

According to an aspect of the present disclosure, a display device includes a display panel, a first back cover supporting the display panel on a rear surface of the display panel, a roller around which the display panel and the first back cover are wound, a pad glass disposed on the rear surface of the first back cover and including a plurality of pads disposed thereon, a plurality of flexible films bonded to the pad glass, and a plurality of side lines electrically connecting the plurality of pads of the pad glass and the display panel. Accordingly, the plurality of pads is separately formed from the display panel so that any stress which may be transmitted to the plurality of pads and the plurality of flexible films when the display device is wound or unwound can be minimized.

What is claimed is: 
     
       1. A display device, comprising:
 a display panel; 
 a first back cover which supports the display panel on a rear surface of the display panel; 
 a roller around which the display panel and the first back cover are wound; 
 a pad glass which is disposed on a rear surface of the first back cover and has a plurality of pads disposed thereon; 
 a plurality of flexible films bonded to the pad glass; and 
 a plurality of side lines which electrically connects the plurality of pads of the pad glass and the display panel, 
 wherein the first back cover includes:
 a plurality of first openings which overlaps at least a part of the display panel; and 
 a second opening into which the pad glass is inserted. 
 
 
     
     
       2. The display device according to  claim 1 , wherein the pad glass includes a plurality of first protrusions which protrudes from one edge which overlaps the plurality of flexible films, among a plurality of edges, and
 the first back cover includes a plurality of second protrusions which protrudes towards the plurality of first protrusions from an edge of the second opening. 
 
     
     
       3. The display device according to  claim 1 , wherein the display panel includes a plurality of side pads which is disposed on a side surface of the display panel and a part of a top surface extending from the side surface, and
 the plurality of side pads is electrically connected to the plurality of side lines. 
 
     
     
       4. The display device according to  claim 3 , further comprising:
 a first seal member which encloses the display panel while exposing the plurality of side pads; and 
 a second seal member which covers the plurality of side lines. 
 
     
     
       5. The display device according to  claim 4 , further comprising:
 a third seal member which overlaps the plurality of flexible films and is disposed between the pad glass and the first back cover. 
 
     
     
       6. The display device according to  claim 3 , further comprising:
 an auxiliary layer disposed between the plurality of side lines and the display panel, 
 wherein an outer side surface of the auxiliary layer includes a curved surface. 
 
     
     
       7. The display device according to  claim 1 , further comprising:
 a printed circuit board which is electrically connected to the plurality of flexible films; and 
 a cover unit which covers the printed circuit board, the plurality of flexible films, the pad glass, and the plurality of side lines. 
 
     
     
       8. The display device according to  claim 7 , wherein the cover unit includes:
 a first cover plate which encloses the plurality of side lines and a side portion of the display panel on one surface of the first back cover; and 
 a second cover plate which encloses the printed circuit board, the plurality of flexible films, and the pad glass on the rear surface of the first back cover. 
 
     
     
       9. The display device according to  claim 8 , further comprising:
 a second back cover including a first end connected to one end of the first back cover and a second end connected to the roller, 
 wherein the second back cover extends between the first cover plate and the second cover plate. 
 
     
     
       10. The display device according to  claim 8 , wherein the roller includes:
 a groove portion; and 
 a curved surface portion extending from the groove portion. 
 
     
     
       11. The display device according to  claim 1 , wherein a size of each of the plurality of first openings is different than a size of the second opening. 
     
     
       12. The display device according to  claim 1 , wherein the plurality of flexible films is electrically connected to the display panel. 
     
     
       13. The display device according to  claim 1 , further comprising:
 a plurality of support areas; and 
 a plurality of malleable areas, 
 wherein the plurality of first openings is only disposed in the plurality of malleable areas. 
 
     
     
       14. The display device according to  claim 1 , further comprising:
 a plurality of second openings; and 
 a plurality of pad glasses, 
 wherein each second opening of the plurality of second openings is configured to receive one pad glass from the plurality of pad glasses.
